What are you trying to achieve?: trial randomization
I do use 2 different sound files and use 2 lines of stimtracker to deliver DC pulse for haptic stimulator. Participants’ response will be collected via voice-key.
In my experiment, I have 8 different types of trials in one block.
So 4 trials are unimodal and remaining 4 would multimodal.
In the block, each trials should be repeated exactly 10 times.
Therefore, there will be 80 trials in one block and I want to randomize these 80 trials.
Here are details for components in different types of trials
Trial 1-2: 1 sound component with 1 code component for voice key (Sounds files between trial 1 and 2 are different)
Trial 3-4 : 1 code component for pyxid with 1 code component for voice key (Code component for pyxid activates different lines between trial 3 and 4).
Trial 5,6,7,8: 1 sound component, 1 code component for pyxid, and 1 code component for voice-key (Trial 5,6,7,8 have its own combination).
What did you try to make it work?:
I looked at Demo for trial and blocks but I do not know how to apply demo for my experiment. Demos have different image files in the one folder. But my experiment doesn’t fall into that setting, especially for pyxid-stimtracker.
First, I uploaded cvs files for each trial that has its own condition file with 10 different labels.-For each condition, I found that sequential or random do not have any effect because I repeat it 10 times. Then I tried to loop all 8 trials under block with fullRandom.
Second, I did another way. each trial has its own condition with only with 1 label. Then I tried to loop them with 10 conditions of the block. This method also didn’t work.
What specifically went wrong when you tried that?:
Include pasted full error message if possible. “That didn’t work” is not enough information.
I did not have error message.
Thank you so much for your comments /advice in advance.
